Hello, I’m Jo Won-jin, director of Chai Clinic.

Over the past 9 years performing lifting procedures in Hongdae, I have met many people who were stressed about facial line management. Whenever that happens, there is something I always emphasize.

Ulthera is certainly an excellent procedure for improving facial contours, but it is not suitable for everyone.

Ulthera is a lifting treatment that uses HIFU, or high-intensity focused ultrasound. It works by delivering ultrasound thermal energy deep into the SMAS layer without damaging the skin surface, causing the tissue to contract. It is specialized for sharpening facial contours, so it can help define the jawline and create a V-line.

However, if you receive the procedure without accurate information, you may end up with results different from what you expected, so please make sure to check the 3 points I’ll mention today.

Ulthera’s “3” Key Points

First point: Check whether your skin condition is suitable for Ulthera

The first thing people looking into Hongdae Ulthera should check is their own skin condition.

Ulthera is a procedure suitable for people with a certain amount of volume in the face. It can be especially satisfying for those who succeeded in dieting during vacation but still have remaining fat in the facial area, particularly those worried about the area under the jaw or double chin.

On the other hand, people with very little fat in the face may experience sunken cheeks because the fat shrinks after Ulthera. It is often not recommended for those with thin skin and generally weak skin elasticity.

You may be wondering, "How can I tell whether I’m suitable for Ulthera?" This can be determined accurately through a detailed skin analysis such as MarkView. Since no two skins are the same, personalized consultation is essential.

Second point: Be sure to check whether a genuine tip is being used

One of the most important safety points in an Ulthera procedure is whether a genuine tip is used. In some cases, recycled tips are used; this means a previously used genuine tip is recharged and reused, which greatly increases the risk of side effects.

Ulthera tips have a thin membrane on the part that touches the skin directly, and if it is reused, the membrane can tear and irritate the skin. This can cause not only burns but also various side effects such as blisters. If you are looking into Hongdae Ulthera, it is good to know these characteristics in advance before visiting.

There are two ways to check for a genuine tip.

First, you can verify authenticity using the QR code on the Ulthera genuine product certification sticker.

Second, you should be cautious about prices that are too low. A genuine tip is disposable and can be used for about 2,400 shots, so it naturally cannot be very cheap.

Third point: Understand the operator’s experience and Ulthera’s characteristics

Ulthera is a device that allows treatment while viewing the inside of the skin in real time with DeepSEE technology. It can also deliver energy at various depths such as 1.5 mm, 3.0 mm, and 4.5 mm, making customized treatment possible according to each person’s skin condition.

However, to make proper use of these technical advantages, the practitioner’s skill is extremely important. To reduce side effects and achieve satisfying results, I recommend visiting a dermatology clinic with sufficient treatment experience.

It is also important to understand the improvement process of Ulthera. Since it improves gradually after the procedure, receiving it now after vacation can help you reach your best condition during the autumn season. As the skin becomes firmer and wrinkles smooth out, the process of collagen regeneration and remodeling from within appears over 1 to 3 months.

For those considering Hongdae Ulthera, it is important to fully understand these characteristics and have realistic expectations.

Summary

To summarize the 3 points mentioned today: check your skin condition, confirm whether a genuine tip is being used, and understand the practitioner’s experience and the procedure’s characteristics.

Concerns about refining your line after vacation are completely understandable. However, since Ulthera is not suitable for everyone, in some cases other lifting treatments such as Thermage FLX or Thermage may be more appropriate.

Above all, it is important to choose a procedure that suits you through an accurate analysis of your skin condition and a detailed consultation. Rather than making a hasty decision, I recommend approaching it carefully based on 충분한 information.

I hope this was helpful for those looking into Hongdae Ulthera, and I’ll wrap up here.

This was Chai Clinic, customizing your beauty. Thank you.
